Patented Get. 22, 1929 UNITE STATES JAMES R. WELTON, OF SUB-ANTON,PENNSYLVANIA THREAD GUIDE App1icati0n.fi1ed December 6, 1928. Serial No.324,179.

This invention relates to improvements in thread guides, andparticularly to a novel guide to be employed with a silk thread cleaner.

My present device is designed to guide the silk or cotton through thecleaning blades, and eliminate the wear on such blade's, which areusually made of metal. With my device, which is preferably formed ofporcelain, the

silk rides on specially shaped surfaces at the front of the device, andthe back portion of the guide is shaped to distribute the silk on thebobbin, and provide a better bobbin, as this guide prevents the silk atthe'rear of the 1:; guide from moving back and forth.

One of the objects of the invention is to furnish a thread guidepreferably composed of vitreous material, porcelain for example, and ofsubstantially inverted U-shaped in side elevation, the top of the guidehaving a longitudinally extending V-shaped groove which merges into avertical slot that is de signed to receive the thread and guide the samethrough the cleaner. I

A further object is to furnish a thread guide of this character, havinga front extension provided with a U-shaped surface that is curved tofacilitate the riding of the silk back and forth, as it is coming off ofthe bobbin or skein, and passing to the cleaner.

With the foregoing objects outlined and with other objects in view whichwill appear as the description proceeds, my invention consists in thenovel features hereinafter des-.

cribed in detail, illustrated in the accompan' ing drawing, and moreparticularly pointed out in the appended claims.

Referring to the drawing,

Fig. 1 is a side elevation of my improved guide shown applied to athread cleaner.

Fig. 2 is a front elevation of the same.

Fig. 3 is a top plan view.

Fig. 4 is a rear elevation of the guide.

Fig. 5 is a horizontal sectional view taken on line 5-5 of Fig. 1.

Fig. 6 is a vertical sectional view of a detail on line 6-6 of Fig. 2.

In the drawing, 1 designates the base or frame of a thread cleanerprovided with cleaning'blades 2 which may be moved toward or away fromeach other to vary the width of the slot 8 between the blades, A silk orcotton thread may be fed from a bobbin or skein through this slot, andthen be wound on a second bobbin and as is usual in such devices, theblades clean the thread as it is being wound on the quill or bobbin,preparatory to weaving. The blades catch or remove snarls, bad knots,wax, gums or the like.

It is the purpose of my invention to provide a novel guide for use withsuch cleaners and one which will eliminate the wear on the cleanerblades and provide a surface on which the thread may ride and anothersurface to facilitate the ditribution of the silk on the quill or bobbinthe last mentioned surface being formed on the wall of a narrow slotwhich will prevent the thread from whipping back and forth on thecleaner blades as it is being wound on the bobbin.

As shown in the drawing, this improved guide 4 is preferably made ofsome vitreous substance such as porcelain, and in side elevation thisguide is of inverted U-shape with the front leg 5 extending downwardlybelow the rear leg 6 and provided with a pin 7 to be inserted through ahole in the base 1, for securing the guide in position. The guide is aone-piece structure, so that it'may be readily installed or removed.

A narrow longitudinal slot8 is vertically arranged "through the deviceand extends through the top or crossbar 9, as well as through the legs,and the cross bar has a longitulinally extending upwardly flaring orV-shaped groove 10 to facilitate the introduction of a thread into theslot. At this point it may be noted that the slot in the guide is inalignment with the slot between the cleaning blades, and that the wallsof the slot of the guide receive any whipping actionof the threads, andprevent such action being applied to the cleaning blades.

'lhe front ends of the side walls of the groove are curved as shown at11, and these curved surfaces merge into vertically disposed curvedsurfaces 12 that join the front ends of the walls of the guide slot tothe front surfaces 13 of the'front leg.

An extension 141 is provided at the extremity of the front leg, and thisextension projects forwardly and is provided with a U-shaped surface 15that is curved from the guide slot to the side edges 16 of theextension, as well as to the edge 17 of the extension, and due to thisformation, it will be understood that the thread passing from the skeinor bobbin through the cleaner, may readily ride back and forth on thisU-shaped curved surface without interference; On the other hand, theparallel walls 18 at the rear end of the slot merge into a planevertical transverse surface 19, formed on the rear legyand as the slotin the rear leg is only about onesixteenth of an inch wide, it willbeseen that the thread in leaving the guide, will be pre vented frommoving back and forth, so that it will be more evenly distributed on there-' ceiving bobbin.

From the foregoing it is believed that the construction, operation andadvantages of the invention may be readily understood by those skilledin the art, and I am aware that various changes may be made in thedetails disclosed without departing from the spirit of the invention, asexpressed in the claims.

What I claim and desire to secure by Letters Patent is:

1. A thread cleaner guide of substantially inverted U-shape in sideelevation, and having a front leg, rear leg and cross member throughwhich a narrow slot extends, said legs beingspaced apart to permit theinsertion of a thread cleaner between the same.

2. A thread cleaner guide of substantially inverted U-shape in sideelevation, and having a front leg, rear leg and cross member throughwhich a narrow slot extends, the cross member having a longitudinallyextending substantially V-shaped groove merging into said slot, saidlegs being spaced apart to permit the insertion of a thread cleaner between the same.

3. A thread cleaner guide of substantially inverted U-shape in sideelevation, and having a front leg, rear leg and cross member throughwhich a narrow slot extends, the rear surface of the rear leg being in aplane at right angles to the walls of said slot, said legs being spacedapart to permit the insertion of a thread cleaner between the same,

4. A thread cleaner guide of substantially inverted U-shape in sideelevation, and having a front leg, rear leg and cross member throughwhich a narrow slot extends, the front leg having vertically disposedcurved surfaces which join the front surface of the front leg to thesurfaces of the side walls of the slot, said legs being spaced apart topermit the insertion of a thread cleaner between the same.

5. A thread cleaner guide of substantially inverted U-shape in sideelevation, and having a front leg, rear leg and cross member throughwhich a narrow slot extends, the cross memher being provided w1th alongitudinally extending horizontally disposed groove, having curvedsurfaces at its forward end merging into the front surface of the frontleg, said legs being spaced apart to permit the insertion of a threadcleaner between the same.

6. A thread'cleaner guide of substantially inverted U-shape in sideelevation, and having a front leg, rear leg and cross member throughwhich a narrow slot extends, an extension projecting forwardly from thefront leg, said extension having a U-shaped curved surface merging intothe walls of said slot, said legs being spaced apart to permit theinsertion of a thread cleaner between the same;

7. A thread guide for use with thread cleaners, formed of a single pieceof a vitreous substance, and of substantiallyinverted U-shape insideelevation, said guide having front and rear legs joined by a crossbar, the guide being provided with a longi tudinally extendingvertically disposed slot which passes through the l'egs and acres thebar, said cross bar having a longitudinally disposed upwardly flaringgroove merging into said slot, the rear surface of the rear leg beingarranged at right angles to the walls of the slot, and the front leghaving an extension and curved-surfaces to permit a thread to ride backand forth on the front leg-and into said slot, said legs beingspacedapartto per mit the insertion of a thread cleaner between the same.
